go to the doctor. an enlarged prostate doesn't mean you have cancer. you may have the symptoms of not being able to urinate and that is common in men over 55. you should have a regular physical exam yearly. symptoms vary but unexplained weight loss is big symptom.

Except for skin cancer, cancer of the prostate is the most common malignancy in American men. It is estimated that nearly 221,000 men in the United States will be diagnosed with prostate cancer in 2003. in most men with prostate cancer, the disease grows very slowly. The majority of men with low-grade, early prostate cancer (confined to the gland) live a long time after their diagnosis. Even without treatment, many of these men will not die of the prostate cancer, but rather will live with it until they eventually die of some other, unrelated cause. nevertheless, nearly 29,000 men will die of prostate cancer in 2003.

Prostate cancer often does not cause symptoms for many years. by the time symptoms occur, the disease may have spread beyond the prostate. when symptoms do occur, they may include:
Frequent urination, especially at night
Inability to urinate
Trouble starting or holding back urination
A weak or interrupted flow of urine
Painful or burning urination
Blood in the urine or semen
Painful ejaculation
Frequent pain in the lower back, hips, or upper thighs

These can be symptoms of cancer, but more often they are symptoms of noncancerous conditions.

Two tests can be used to detect prostate cancer in the absence of any symptoms. one is the digital rectal exam (DRE), in which a doctor feels the prostate through the rectum to find hard or lumpy areas. The other is a blood test used to detect a substance made by the prostate called prostate specific antigen (PSA). Together, these tests can detect many “silent” prostate cancers, those that have not caused symptoms

Prostate cancer usually doesn't cause symptoms in its early stages. Between 60% and 70% of men who are older than 80 who have prostate cancer have no symptoms.

When there are symptoms, they may include:
*Difficulty urinating
*An urge to urinate even when the bladder is empty
*Frequent urination, especially at night
*A weak or intermittent stream of urine and a sense of incomplete emptying when urinating
*Pain or burning during urination
*Chills and fever along with urinating problems
*Difficulty starting urination. This is called hesitancy.
*Inability to urinate
*Weak or interrupted flow of urine (dribbling)
*Having pain or a burning feeling when you urinate. This is called dysuria
*Painful ejaculation
*Blood in urine or semen
*Frequent pain or stiffness in the back, hips, upper thighs, abdomen, or pelvis.

Blood in urine to start, problems peeing and always wanting to pee. Terminal, seek pro advice.

this is quite an obscure question so is hard to answer without more details.

initially men may experience difficulty in passing urine. the prostate gland increases in size and therefore hinders the passage of urine. men will have difficulty emptying their bladder fully. this leads to frequency of needing to pass urine, urgency to pass urine and increased need to get up and pass urine. urine infections also can occur due to poor bladder evacuation.

as the disease progress these symptoms may increase..there may be pressure down bellow and they may experience constipation. there may be blood in the urine and as it really progresses and the cancer spreads (often to the bones), they may experience bone pain.

i was a senior staff nurse on a surgical ward for some years and if this is related to you or someone you know i suggest you see your GP asap for an examination and blood test.

all the very best. please remember this advice is unqualified and you need to see a GP for diagnosis.

Don't watch and wait go to your GP and ask to see a specialist
your local GP normally has little knowledge believe me I KNOW

initially you will have trouble urinating after a digital check and a psa blood test you may get an mri and or a needle biopsy
there are many ways to treat the disease including surgery and radioactive seeds
